Not sure what you are asking.

You aren't going to gain a thing by tuning a 4.7 gas mileage wise and probably not performance wise either. Best thing you can do is keep up on all the maintenance and drive her easy and slow to maximize fuel economy. The 4.7 is basically underpowered for the heavy ass RAM.

I pulled 250rwhp from a 2013 4.7,which is pretty close to what a stock 3rd Gen Hemi puts down at the tires,it also averaged a little over 21mpg at 65mph.
Link to my old build on it.
